Application tiled January Z9, 1906. Serial No. 298,384.

To all 'wh/om, it may conc/:77+:

Be it known that I, CHARLES Iiiionseniiti., a citizen of the United States, residing at ("liicago, in the county of Cook and State of Illinois have invented. a new and useful Iin- 7 Y, s l n provenient in Boiler' (,onstruction, of which the following is a specification` Mv invention relates paiticularly to boiler installatii'in; and my primary object is to i provide a safety connection between a pipe leading from the boiler and the masonry wall The shell c, which may otherwise be termed an f open-ended box, is securely embedded in the masonary of the wall and affords a passage through which the pipe B normally extends centrally with suflicient space above ahd below the pipe to permit relative movenent of the pipe with relation to the wall. Il"

through which the pipe extends, whereby l breakage of the pipe connections, due to the settling of the boiler, may be obviated.

The invention is illustrated in the accompanyii'ig drawings, in which Figure l represents a vertical sectional view of a boiler eduipiied with my improvement; Fig. 2, an outer end elevational view of a frame set into a wall of the boiler and constituting a portion of niy invention; Fig. 5%, an elevational view of a shiftable self-adjusting plate connected with said frame, and Fig. #L a broken section taken as indicated at line 4 of Fig. l.

ln the construction illustrated, A represents a boiler iiiclosed in a casing A', of masonry; B, a pipe connected with the lower rear portion of the boiler and which may serve as a blow-olf pipe and also as au injection-pipe, and (l a self-adjustii'ig slip-joint connection between the pipe B and the rear wall (l of the chamber containing the boiler.

The device comprises a shell or frame c of rectangular 'forni and a slide c vertically movable in guides c2, with which the outer end of the shell c is provided. The shell c comprises two sections c c", which are connected together at a longitudinal central vertical plane c5 by means of lugs c. The oiitei' end of the shell is flanged, as shown in Figs. l. and 4, the flange fitting against the outer surface of the wall a. The shiftable plate c/ is provided with a central opening c7, which v[its more or less snugly upon the horizontal portion of the pipe B. The plate comprises an upper section as and a lower section C, the meeting plane of which is at the axis of the opening c7. The sections are .provided with flanges c1, connected by bolts cu.

the boiler settles with relation to the wall or the wall settles with relation to theboiler, the plate c will move within the guides c2, thereby preventing breakage. At the same time a close connection between the pipe and. the wall is maintained und er all conditions. Th1` sectional construction of the parts enables them to be applied after the boiler is installed, and where it is desired to apply the device to a boiler already in use a sufficiently large opening to receive the shell is provided, after which the. space between the shell and the wall may be vfilled in with cement.

The preferred construction is described in detail for clearness of understanding only.

Vnat I regard as new, and desire to secure by Letters Patent, is-- l The combination of a boiler, a pipe connected therewith, a chamber-wallthrough which said pipe extends, a guide connected with said wall, and a plate having a perforation tting upon said pipe, said plate movable in said guide, for the purpose forth.

2. The (,ioinbination of a boiler, a pipe connected therewith, a chaiiiber-wall provided with an opening, a. thimble inserted in said opening and equipped at its outer end with a guide, and a plate having a perforation receiving said pipe, said plate movable in said guide, for the purpose set forth.

3. The combination of a boiler', a pipe connected therewith, a chamber-wall having a perforation through which said pipe extends,

i a sectionally-constructed thinible inserted in said perforation and equipped at one end with a guide, and a plate Vfitted upon said pipe and movable 1n said guide, tor the purpose set fortl i CHA R LES KB OESCII El ,I i.
